Hello, first, sorrry if my question is off topic here, as it is "stills related"... but this is the only 7D forum I am registered at 
With my 7D, The pictures taken with the liveview (LCD screeen) are sharper than the ones with the viewfinder...It happens with all my lenses, at any speed, operture...
Here is a crop 100%, shot with a Tokina at 11 mm, f2:8 1/160, on a tripod

Liveview shot is on bottom
And another 100% crop, shot with a Canon 50 mm f2:8, 1/100 on a tripod as well

Liveview shot is on the left
The shop where I bought the camera tells me this is absolutely normal. Is it really?
Thanks a lot for your help !
